Answer:
b) Economies of scale
Explanation:
In general, value-creating diversification of General Electric under Jack Welch was Economies of scale.
He shut down factories, set workers loose, and offered a promise of "growing rapidly in a slow growth economy," titled a speech he made in 1981 shortly after he became President.
This period of mass restructuring gave him the surname of Neutron Jack when he took people out, much like a neutron bomb as he left the houses.
